General Description
PS4502 is a single channel LED driver with constant current sink function. PS4502 has excellent temperature stability and output current accuracy over a wide supply voltage range from 7V to 40V. Several fixed output current versions provide a simple way to drive LEDs. A maximum voltage rating of up to 60V makes the PS4502 suitable for most DC supply voltage LED lighting applications. The PS4502 has an extremely small 426um x 745um form factor and can be assembled with LED chips in miniature devices such as COB, light strips, lamps … etc. And, it will not be damaged by high temperature with the features of a current ramp-down function from junction temperature 125o C to 145o C.
There are two ways to integrate...
